3 ALU Software Design Primary Purpose: Support reporting of GHG emissions to the UNFCCC Greenhouse Gas Inventory Software Program Developed for LULUCF and Agricultural Sectors Based on IPCC methods (96 GL and GPG) Emphasis on incorporation of good practices Accommodates IPCC Tier 1 methods, but allows compilers to advance inventory with the Tier 2 method capability User-interface guiding compiler through inventory process of data entry and calculations

4 ALU Software Design Data management capability Relational database Activity data, emission factors, emission results Can incorporate GIS-based data on land use and land use change derived from remote sensing imagery Documentation and archive for all data and results Self-contained database with data used in inventory as well as documentation references and results Institutional memory for long-term sustainability of GHG inventory Includes an electronic help manual Step by step guidance for software users

5 ALU Software & Good Practice Inventories following good practice contain neither over- nor under-estimates so far as can be judged, and which uncertainties are reduced as far as is practicable (IPCC GPG 2000). Estimate uncertainties Quality Assurance/Quality Control Document inventory methods and emission factors, and archive the database Development of Tier 2 methods for key source categories

6 Inventory Purpose: Reporting One of the main purposes of a national GHG inventory is to report emissions to the UNFCCC Reporting is generally done in spreadsheets Maps can be useful for illustrating variation in emissions across a country ALU provide emission reports that conform to the typical non-annex I party reporting standards (i.e., UNFCCC software spreadsheet) ALU facilitates the development of emission maps to the extent that activity data and/or emission factors vary spatially

7 Inventory Purpose: Mitigation Analysis Inventories should form the basis to consider mitigation options and monitor outcomes of policy actions intended to reduce emissions (NAMAs and LEDS) With an inventory developed using good practices, compilers can be confident in assessing mitigation potentials ALU facilitates mitigation analysis using the GHG inventory developed in the software with good practice for the baseline emissions

28 Example: ALU Mitigation Analysis

29 Scope of Analysis Analyze the potential change in greenhouse gas emissions from changing management of land and livestock Use existing inventory in ALU as the baseline Include multiple source categories influenced by practice Within Agriculture and LULUCF Biophysical potentials estimated by ALU, but projections can be informed by economic forecasts of commodity production and consequences for management of land and livestock

30 Approaches for Mitigation Analysis Whole Session Approach Focus on all practices Maximum utility Assesses all drivers of emissions and mitigation potential Population growth, economic growth and technology Practice-Based Approach Focus on specific practice Assesses technology as a driver of emissions and mitigation potential

34 Enter Mitigation Projection for Burning

35 Enter Mitigation Projection for Burning
